PUMP APPARATUS.

Application filed December 15, 1923. Serial 1T0. 680,997.

To all whom it may concern:

Be it known that I, SIDNEY L. MENGE, a citizen of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in Pump Apparatus; and I do hereby declare the following to be a full, clear. and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to improvements in pump apparatus and more particularly consists in the provision of an apparatus for use in connection with the crank cases of automobiles, and other motors wherein a three fold operation is had; firstin draining the waste oil from the crank case, secondly to" inject into the crank case a washing oil which is subsequently removed, and thirdly to replenish the crank case with fresh lubricating oil.

An object of the invention is to secure this three-fold result in a compact portable apparatus particularly useful in connection with the service stations at which automobiles secure gasoline, lubricating oils and accessories.

Other objects of the invention are to pro-.

scribed hereinafter, and will be particu larly pointed out in the claims appended hereto. In the drawings, wherein like symbols refor to like or corresponding parts throughout the several views,

Figure-1 is a top plan view, with parts broken away, showing a pump apparatus constructed according to the present inven-' tion. I

Figure 2 is a side view thereof, and Figure 3 is a rear view of the apparatus. Referring more particularly to the drawings, 4 designates a platform or carriage supported on the rear wheels 5 and the front wheels 6, there being a tongue or other appropriate device 7 by which the front wheels maybe guided and the vehicle moved to the location desired; for instance, to a point proximate to the engine or vehicle from which the oil is to be drained and new oil supplied after cleaning the crank case.

Upon the latform are assembled in any desired relative locations the various units comprising the apparatus. In the embodiment "shown an electric motor 8 constitutes the source of power, and this motor is installed at the front of the platform or the carriage, being connected through the shaft 9 journalled in appropriatebearings to the pump 10, which may be of any suitable ty e,

for instance, a rotary reversible pump. e

electric motor 8 is also of the reversible type, and is controlled through a double t row switch 11 mounted adjacent thereto or in a position convenient to the hand of the operator. The electrical connections are not shown asthey form no part of the present invention, and it will be clear to those skilled in the art that the switch 11 in one position will cause the motor 8 to be driven in one rotary direction, for instance, in a clockwise direction, while the other position of the switch causes the electric motor to rotate in a counter clockwise direction, the pump 10 being driven accordingly. The pump 10 at one side is connected with a flexible hose 12 which may be introduced at its open free end into the crank case of the engine either through the drain plug or through the top filling neck. For this purpose the breather cap is, of course. first removed from the filling neck, and the end of the hose, which will be of a suitable length for this purpose, may be pushed down to a low olnt 1n the crank case so as to draw all 0 the used or waste oil therefrom.

' The ump at its other side is connected to 24 and 25. The manner ofconnecting the severalpipes 14, 15 and 16 with the compartments is shown in Figure 3, the compartments being provided with sloping bottoms 26 and-the pipes being connected to the bottoms at the lowest points thereof by the conand the wash oil is through the nections 27. The pipes 15 and 16 extend out beyond the connections 27 on to the other side of the tank .or carriage, and are provided with downturned ends and with valves 28 and 29.

Of course, separate tanksmay be used instead of a single tank with the partitions, the tank or tanks bein supported at an elevation from the plat o'rm as indicated in Figure 2 to admit the pipe branches therebeneath.

In the use of the device, the tank or compartment 23 is charged with fresh lubricating oil; the tank or compartment 24 with a 1 light lubricating wash oil, and a third tank or compartment 25 is initially empty. The apparatus is moved up to a motor and the hose 12 is connected either with the drain or introduced through the filling neck as above indicated. The valves 17 and 18 are closed and the valve 19 is opened, the drain valves 28 and 29 being, of course, closed. The motor 8 is then put into operation by closing the switch 11 in such wise that the pump 10 will be driven as a suction pump to draw the used oil out of the crank case through the hose 12 and force this used oil pipe 13 and the branch pipe 16 into the empty compartment or tank 25. When all of the oil has thus been removed from the crankcase, the motor is stopped, the valve 19 closed, and the valve 18 opened. The switch 11 is then thrown to the opposite position to cause the motor and pump to rotate in a reverse direction. The wash oil is thus drawn from the center compartment or tank 24. and injected into the crank case. After a suitable quantity of the wash oil is circulated in the crank case, and possibly the motor run for a short while with the wash oil in said crank case, the motor and pump may be again reversed to cause removal of this wash oil from the crank case preferably delivered to the tank or compartment 25 by opening the valve 19 and closing the valve 18 during this stage of the operation. Preferably two. or more charges of the wash oil are circulated through the crank case in the manner just described, and after the last charge has been removed, the valves 18 and 19 are closed, and the valve 17 is opened, the motor and pump being so driven through the control of the switch. 11 as to cause the fresh lubricating oil in the tank or compartment 23 to be pumped into the crank case in a suitable quantity depending upon the capacity of the crank case. i The valves 28 and. 29 are only opened when it is desired to drain the tanks or compartments 24. and 25. When the tank 25 is filled with the thin used oil, the valve 29- may be o ned and this oil drained out into a. suitablii container used for lubricatin springs or for other purposes for which it s said pump, and a reversible suitable or it may be discarded. The various valves are preferably quick opening valves of any suitable type in order to facilitate the operation as it is very important to be able to take care of the customer without any delay.

It is obvious that various changes and modifications may be made in the details of construction and design of the above specifically described embodiment of this invention without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the folowing claims.
